Charlie and Lola are excited because Christmas is coming and they are taking turns opening the doors on the Advent calendar. Plus, this year Lola put an extra special gift for Charlie on her wish list to Santa. After 24 days of hiccups and happy preparations, Christmas caroling and making things, everything looks set for the perfect Christmas-- until Lola notices that she sent Lotta's Christmas card to Santa and her Christmas wish list, with that special gift request for Charlie, to Lotta by mistake. Things couldn't possibly get worse until Lola discovers that there is no door on the Advent calendar for Christmas Day. Christmas has completely disappeared and definitely is not going to happen. It's an absolute disaster-- or is it?
